T0 @ZZ whom, 71T? muy coltccrn/ Be it known that I, SAMUEL M. PETERSON, a citizen of the United States, residing at Kent, in the county of Wilkin and State of Minnesota, have invented certain new and useful Improvements in Grain-Elevators 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the sam e.

My invention relates to improvements in to provide a portable device whereby grain may be elevated from wagons in vwhich itis placed loosely in tanks to a granary.

The invention resides particularly in an improved portable treadmill which can be readily raised and lowered from one end and means for transmitting the power from said treadmill to operate a feed-conveyer in a hopper located at the front of the machine or for any other purpose that it may be desired to use the same.

The invention consists of a main frame mounted upon suitable wheels, a tilting treadmill-frame mounted upon the rear axle of the machine, segmental racks at the forward end of said tilting frame, pinions mounted upon the opposite ends of a horizontal shaft en gaging said racks, a worm gear-wheel on said shaft, and a worm acting in engagement with said worm-wheel, through which said shaft is turned for the purpose of raising or lowering said tilting frame. Mounted on suitable drums at the front and rear ends of said tilting frame is a tread .belt or apron having sprocket-chains attached thereto, which engage corresponding sprocket-wheels on the rear-drum shaft, and a series of rollers on the inner side of said tread-apron, which are adapted to engage a metal track on the under side of said tilting frame. Suitable means are provided for lengthening the distance between the drum-shafts for tightening the sprocket-chain of said belt or apron. A brake is provided for stopping the rotation of one of said drum-shafts, and suitable connections are made between the rear-drum shaft and a sprocket-wheel on the rear axle, by means of which the power is transmitted from the tread apron or belt to said sprocket-wheel. Engagingbeveled teeth on said sprocket-wheel is a beveled pinionattached to the rear end of a shaft mounted in suitable bearings and extending to the forward end of Ithe machine, a suitable clutch mechanism being provided for throwing said shaft into and out of engagement with -theteeth o n said sprocketwheel. At the front of the machineis located a hopper for receiving the grainin bulk direct from the tanks in the wagons in which it is conveyed from the threshing-machine, which hopper is provided with an opening in the bottom thereof, with a suitable sliding cut-off therefor, and a con veyer belt or apron moving around suitable guides beneath sa'id opening and driven through a belt or sprocket-chain meshing with the sprocket-wheel on the forward end of said longitudinal shaft. Adjacent to one end of said hopper, at the front of the device, is an elevator made up of two parts, by means of which it may be extended to Vaccommodate it to different heights of granaries, with means provided for raising one lot' the parts and adjusting it at any desired elevation. llhedifferent parts are adapted to be folded up in compact form and loaded in `0n the top of the tilting frame for convenience in transporting the same from one point to another.

The invention also consists in other details of construction and combinations of parts, which willbe hereinafter more fully described and claimed.

In the drawings forming part of this specification, Figure l represents a perspective view of my device with allthe parts thereofshown in closed position, or the positions which they assume when the machine is to be moved from one point to another. Fig. 2 is a similar view showing the parts set up in operative position. Fig. 3 is a top plan view of the same. Fig. 4 is a central longitudinal section.

Like reference-n u merals indicate like parts in the different views.

The main frame of my machine is suitably supported upon front and rear axles 1 2, respectively, having wheels 3 4C upon the outer ends thereof. The said main frame is made up oftwo parallel longitudinal beams 5 5, which are securely connected to the rear axleJ and a front cross-beam 6, which is pivot-ally connected at its central point to the front axle 1. The cross-beam 6 has attached toits upper ends a horizontal beam or platform 7, through which extends a vertical shaft 8, having a worm 9 upon the lower end thereof, the said shaft having bearings at its extreme lower end in a projection 10 on the front side of the cross-beam (i. On the upper side of the horizontal beam 7 is a horizontal rod or bar 11, which is connected at its outer ends to brackets 12 12. The outer en'ds of the cross-beam (i have connected to them upright .beams 13 13, in the` upper ends of which is mounted a horizontal shaft 14E, provided with a worm gear-wheel 15, which meshes with the worm 9 on the shaft 8 and has connected to its outer ends pinions 1G 16for a purpose which. will appear hereinafter.

Mounted in bearings on the rear axle 2 and extending to the forward end of the machine is a tilting tread-frame 17, having upright side pieces 1S 1S, which are adapted to be held in position by means of detachable connecting-bars 19 19, having flanged plates 2O 20 on their outer ends, which ii't over the top of said side pieces 18. At the rear of the tilting frame 17 is a hinged back piece 21, which is adapted to be held in closed position by means of rods 22 22, having hooked inner ends 23, which engage pins or openings in the side pieces 1S. The said back piece 2l is also adapted to be folded down against the ground, as shown in Fig. 2, so that a horse may be driven up into the treadmill formed by the tilting ,frame 17. At the forward ends of the tilting frame 17 are segmental racks 24.- 24:, which are engaged by the' pinions 1G 1o' on the horizontal shaft 14. Mounted in sliding boxes 25 25 at the rear end of the treadframe 17 is a shaft 2G, upon which is mounted a drum or roller 27, a similar drum or roller 28 being provided at the forward end of the tilting frame 17. The drums 27 and 2S are provided with peripheral grooves 29 2H for a purpose which will hereinafter appear, and the drum 27 has secured to Ait sprocketavheels 30 30 on the inside of the side bars thereof and a sprocket-wheel 3l upon its extreme outer end. 0n the under side of the tilting frame 17 is secured a pair of parallel metal tracks 32, which are supported by a cross-beam 33, extending to the outside of the machine,

the outer ends of said cross-beam being connected by bracing-beams 311, attached to the side pieces 18 1S. Extending around the drums or roller. 27 28 is a tread apron or belt 35, made up of a series of slats 3G 36, which are flexibly connected together by means of sprocket-chains 37 37 on the inner side thereof. The slats 36 are of such a width and the links of the chains 37 are of such a length that just three of said links will equal in length the width of said slats. The center link of the three is bolted to the inner side of cach slat, so that the flexibility of the apron will not be affected and the chains Will be free to move around the sprocket-wheels 30 30 on the rear drum 27. On the under side of each of the slats 3b' of which the belt 35 is composed are secured, just within the chains 37 37, brackets 33 38, in which are mounted, two to each side of said slats, rollers 39 39, which are adapted to engage and form an autifrictional bearing with the upper surface of the metal tracks 32. These rollers also iit within the peripheral grooves or recesses 29 29 in the drums `or rollers 27 2S, so that they do not interfere with the said rollers or prevent the engagement of the sprocketwheels 30 with the chains 37.- At the ends of the two sides of the tilting frame 17, just in the rear of the sliding boxes 25, are brackets 40 40, having screws 41 therein, which engage threaded portions of the sliding boxes 25 for the purpose of drawing said boxes outwardly or forcing the same inwardly to tighten or loosen the sprocket-chains 37, passing around the drum or roller 27 on the shaft 2G.

Ou the drum .17, between the sprocket-wheel 30 thereon and the side of the tilting frame 17, is a smooth pulley 42, around which passes a brakestrap 43, which is connected through a rod or pitman it with one arm of alever 45, fulcrumed in one of the side pieces 18 and provided with a tooth or projection thereon, which is adapted te be inserted into perforations or openings Lt7 in a sector -tcl on the side of the side bars 1S. By this mechanism the rotation of the rear drum 27 may be stopped at any time. Mounted on the rear axle 2 just inside the rear Wheel 4 is a sprocket-wheel 49, around which and the sprocket wheel 30 passes a sprocket-chain for the purpose of transmitting motion from the rear drum 27 to said sprocket-wheel 49. The said sprocketwheel 4-9 has secu red to or formed integral with it a beveled eog-wheel 5l, which meshes with a beveled pinion 52 upon the rear end of a shaft 53, which extends forwardly to the front of the machine. This shaft 53 is mounted in suitable bearings 54,.so that it is capable of receiving a rotary movement, and the front bearings 5a are situated at the lower end of a metallic plate 55, having an elongated slot 56 therein, through which passes a bolt 57 for securing said plate to one of the uprights 13 on the end of the cross-beam (l. A pin 5S is adapted to be inserted into and removed from an opening 59 in the upright 13, so that when IIO plate 55 in its downward position, said plate is held stationary. The said shaft 53 is also adapted to be moved longitudinally in its bearing, this movement being provided for the purpose of disengaging the pinion 52 from the beveled cog-wheel 51. This movement is effected by means of a clutch 60, attached to one end of the shaft 53, adjacent to the pinion 52, and at its other end to an operatinglever 61, fulcrumed in a sector or bracket 62, secured to one of the longitudinal side bars 5 of the main frame. The forward end of the shaft 53 has connected to it a sprocket-wheel 63 for a purpose which will presently appear.

At the front of my device is located the elei vator 64, the rear side thereof being pivotally connected to a block 65, which is in turn pivotally connected to and slidingly mounted upon the horizontal rod 11 on the upper side of the horizontal beam7. The elevator 64: is made up of a pair of upright beams 66 66, supporting the elevator proper. Between the beams 66 is a rod or bar 67, which is adapted to be engaged by a toothed bar 68, pivoted to the block for the purpose of holding the uprights 66 66 securely in vertical position. In connection with the uprights 66 I may also employ a pair of uprights 69 69, constituting a second part of the elevator-frame, which is adapted to be moved up or down for the purpose of accommodating the elevator to different heights of granaries. The two parts of the elevator-frame are sidingly connected together. One part-that composed of the uprights (i6-has secured to it a plate 70, which shall project slightlybeyond the front and having inturned flanges 72, which -surround the edges of the plate 70. On the front of one of the uprights 66 -is mounted a winch or windlass 73, which maybe locked in any position bymeans of the pawl 74, and has a cord wound thereon, which passes around a pulley 76 on the front side of one of the beams 66 and around pulleys 77 77 on the lower end of the upright-s 69, being securely attached to the upper end of one of the uprights 69 on the rear side thereof. By this means the sliding part of the elevator-frame, made up of the uprights 69 69, may be raised or lowered by turning the windlass 73 in one` direction or the other. In the cross-bar 78, which connects the upper ends of the uprights 66, moves a horizontal shaft 79, having a sprocket-wheel 80 upon the rear end thereof, around which passes a sprocket-chain 81, which at its lower end passes around the sprocket-wheel 6 3 on the forward end ofthe shaft 53. `By this means the rotary motion of the shaft 53 is transmitted to the shaft 79. On the front end of said shaft 79 is secured a sprocletwheel 83, which is geared, through a sprocket-chain 84, with a sprocket-wheel 85, secured to a shaft mounted in the crosshead 86 at the upper end of the uprights 69, constituting the movable part of the elevatorframe; The sprocket-wheel is in turn connected, through a sprocket-chain 87, with a sprocket-wheel 88, mounted in the lower end of the elevator-frame 64.

Detachably connected to the front end of the machine is a hopper 89, which consists, essentially, of a boX having a horizontal bottom 90 and vertical sides and end pieces 91 and 92, respectively. The rear side 91 has pivoted toit a clip 93, which is adapted to be inserted through a loop or staple 91 on the cross-beam 6 of themain frame, by meansof which said hopper may be readily attached to and disconnected from said frame. It is also provided with a projecting plate 95, having an opening 96 therein, through which a pin'97 may be inserted for securing said hopper to- -is hinged to the main part of the hopper and is adapted'to be foldedoutwardly, as clearly shown in Fig. 2. This is provided with pivoted bracing-rods 99, having flanges 100 at their inner ends, which are adapted to be inserted into loops or staples 101 and 102, secured to the side pieces 91 of said hopper, so that said end piece may be securely held either in its open or closed position. The bottom of the hopper is provided with an opening 103 and with a sliding cut-off 104, which is adapted to be moved back and forth from the outside of the hopper for the pur- .poseV of opening or closing the orificef103.

The inside of the hopper has a canvas lining 105, which is secured to the bottom around the edges of the opening 103 and isl loosely attached 'ro-other parts of the inside of said hopper. On the under side o f the bottom of the hopper is secured a pair ofr parallel beams 106 106, in which are mounted parallel horizontal shafts 107 108, around which passes a conveyer-belt 109, which is located directly beneath the orice or opening 103l inthe bottom of said hopper. The outer end of the shaft 107 has attached to it a sprocket-wheel 110, around'which passes a sprocket-chain 111, which also passes around and meshes with the sprocket-wheel 88 at the lower end of the elevator-frame 64:.

The ordinary method of transferring grain from the thresher to the 'granary is to lill the same in bags at the thresher, load the bags of grain into wagons, and convey the same to the granary, afterward carrying or elevating the same by hand into said granary. This operation requires a large number of men,

one being necessary at the bagger of the threshing-machine, one being necessary to transfer the bags to the wagon,one bei-ng necessary to operate each team, and others vbein-g necessary'to. transfer the bags from the wagon to the granary. llurthermore,the work that must be performed is the hardest kind of la bor, and the time required is soy great that in order to house all the grain that can be threshed by a single machine a number of different teams are necessary. This adds greatly to the expense, and a further loss is met with by the fact that a great deal of grain is wasted in lling it into the bags and also through openings or holes in the bags themselves. By the use of my invention all this will be overcome and the expense of handling the grain will be materially decreased. I propose to transfer the grain at the threshingmachine directly into tanks on the wagons, the same being elevated by the elevator attached to the threshing-machine. I thereby dispense with the man at the bagger and the man who transfers the bags of grain from the thresher to the wagon, and, furthermore, by the use of the tanks prevent the waste of the grain, which is so common under the old method of procedure.

My improved elevator and portable treadmill is adapted to be transported with ease from place to place, and when set up adjacent to a granary the operation is as follows:

It will be assumed, of course, that the elevator G1 will be adjusted in vertical position, that the shaft 53 will be in engagement with the cog-wheel 51, and that the connections will be made through the forward end of the shaft 53 and the conveyer on the under side of the hopper 89. The grain from the tanks in the wagon is first dumped into the hopper 89, and the orifice 103 therein is closed by the cut-'off slide 104;. lhen the hopper has been lled,the tilting frame 17 having been raised, the treadmill is put into operation by the horse tread-apron 35, which, through the sprocket-wheels 30 on the rear drum 27, acting in engagement with the sprocketchains 37 on the inner side of the belt or apron 35, transmits the motion through the sprocketwheel 31 and the sprocket-chain 49 to the sprocket-wheel 50. rlhe motion is further transmitted through the beveled cog-wheel 5l and the pinion 52 to the shaft 53, having the sprocket-wheel 63 on the forward end thereof. This,through the sprocket-chain 81, sprocket-wheel 80, shaft 79, sprocket-wheel 83, sprocket-chain 84, sprocket-wheel 85, and sprocket-chain 87, transmits the motion to the sprocket-wheel 88 at the lower end of the elevator-frame 64. The operation of the sprocket-wheel 88 causes a forward movement to be imparted to the conveyer-belt 109, which carries the grain from the hopper 89 admitted to said belt through the opening 103 to the elevator. It is then raised in the usual manner. The hinged outer end of the hopper 89 is provided so that the end of the hopper may be inserted directly beneath the opening in the grain-tank on the wagon to prevent the waste of the grain. The canvas lining 105 of the hopper is provided for the purpose of doing away with the necessity of shoveling the grain remaining in the corners of the hopper, it being necessary, in order to force the same through the opening 103, to

merely lift the sides of said lining, which throws the loose grain inwardly.

It should be stated in this connection that the sides and end pieces 91 92 of the hopper 89 are so connected together that they may be readily taken apart for the purpose of transporting the machine. lf a machine is to be hauled a long distance, the hopper 89 will be knocked down and inserted between the sides 18 of the tilting frame 17, resting upon the top of the treadmill or apron 35. At the same time the hinged back piece 21 is folded up into the position shown in Fig. 1, and locked in said position by the engagement of the iuturned ends 23 of the rods 22 with a loop or staple on the side piece 18. When the hopper 89 is disconnected from the front of the machine, the clip 93 is elevated out of engagement with the loopor staple 94 on the cross-beam 6, and the pin 97 is released from engagement with the plates 95 and 98. To fold up the elevator-frame, the pivoted bar 68 is thrown out of engagement with the cross-bar 67 and said frame turned rearwardly on the pivotal connection between the block 65 and the horizontal rod 11. The said frame is then shifted sidewise along its bearing upon said rod and folded rearwardly between the sides 18, resting upon the top of the knocked-down hopper. The detachable shafts 112 are then connected to the front axle 1 in the manner shown and the machine is in position for moving. Before the elevator-frame G4 is folded back, however, the sprocket-chain 8 1 should be disconnected from the sprocket-wheel 63, and the pinion 52 on the inner end of the shaft 53 should be thrown out of mesh with the beveled cog-` wheel 51 by operating the clutch mechanism connected to said shaft 53. The pin 58 should also be removed from the upright 13, and the plate 55, in the lower end of which the bearings 54 of the shaft 53 are formed, should be elevated, as shown in rFig. 1.

Then the horse is in the treadmill between the.sides 18 18, the bracing-rods 10 19 should be adjusted at the cxtreme out-er ends of said sides 18, but when the horse has been removed said brace-bars may be moved closer together, as shown in Fig. 1.

lVhile l have described my invention as being particularly adapted to use for elevating grain, it is obvious that the portable treadmill may be utilized for any purpose that may be desired. For example, a farmer might use the same for pumping his water, cleaning his grain, or operating any other device or machine where power is required. The power of a treadmill is the most economical that can be used by a farmer, is always at hand, and where the treadmill is made portable it may be utilized ,for a variety of purposes for which it has never been employed heretofore.

One of the important features of my invention is the means of mounting the treadmill so as to make it portable and the mechanism ICO IIO

whereby one end of the treadmill may be elevated quickly and conveniently and as quickly and conveniently lowered into place. It is a Well-known fact that it is more fatiguing 5 to a horse to stand upon an inclined plane with his front feet raised than it is to walk. Vhen, therefore, there is any delay or cessation of the work, my tilting frame may be readily and quickly returned to horizontal 1o position, so that the horse is left just as com- I claim as new, and desire to secure by Letters Patent, is-
